Q1: Pick up the correct statement from the following :

ANS:E - all the above.

1. The framework which consists of a series of connected lines, the lengths and directions of which are found from measurements, is called a traverse." This statement defines what a traverse is in surveying. It's a method of surveying where a series of connected lines are measured, and the lengths and directions of those lines are determined through measurements. Traverses are fundamental in land surveying for mapping and determining the positions of various points.
2. "The system of a series of lines which forms a circuit which ends at the starting point, is called a closed traverse." A closed traverse is a specific type of traverse where the series of lines form a closed loop or circuit, and it ends at the starting point. Closed traverses are important because they allow for error checking and adjustment since the final point should ideally coincide with the starting point.
3. "The traverse that starts from a point already fixed in some survey system and ends on another such point, is called a controlled traverse." A controlled traverse is a type of traverse where the starting and ending points are already fixed or known in a survey system. This type of traverse often connects two known points or ties into an existing survey network.
4. "The traverse that is not controlled is called a fly traverse." A fly traverse, also known as an open traverse, is a type of traverse that does not tie into existing control points. It often starts and ends at unknown points, making it less constrained by existing survey control but also requiring more careful adjustment and verification of accuracy.
